The SCP is a retirement savings plan. Generally, you cannot withdraw money from your plan account while you are still employed by your employer.
If you have SCP POFF Rollover Funds, the options below apply:

You may begin taking distributions from your CalPERS account at any time, however, IRS rules governing early distribution penalties may apply if you haven’t attained age 59½. The Plan offers you the flexibility to receive:

• a lump sum
• a partial lump sum
• payments for a specific time period
• payments based on your life expectancy or the combined life expectancy of you and your spouse.

Monthly, quarterly, semi-annual or annual payment options are available and you may change your payment frequency whenever you need to. You may also increase, decrease or cease your benefit payments, unless you have started receiving Required Minimum Distributions after reaching age 73.
